Abstract
- Due to the surging bandwidth demand for applications like 360 ° video streaming, hypertext transfer protocol (HTTP) adaptive video streaming has been extended to fetch contents from a single server to multiple servers. However, when players share a bottleneck link, it fails to hold three critical properties: fairness , efficiency , and stability. Effective algorithms have been proposed to tackle the problem in the single-server case. We revisit the three properties and show that they degenerate in multi-server streaming. In this paper, we propose MultiFast , a protocol that offers the best user experience by achieving fair, efficient, and stable multi-server video streaming. MultiFast consists of (1) a bitrate selection algorithm that ensures fairness with concurrent connections; (2) a connection management algorithm that ensures efficiency and stability by managing connections based on network conditions. Our real-world experiments show that MultiFast achieves the best performance in fairness, efficiency, and stability metrics, outperforming its closest alternative. [Display omitted] • A comprehensive bitrate selection algorithm achieves fairness. • A connection management algorithm achieves efficiency and stability simultaneously. • An in-depth theoretical analysis guarantees the correctness of our design. • Real-world experiments demonstrate the effectiveness.
